A thread pool is a form of multithreaded processing that adds tasks to the queue and automatically starts these tasks after the thread is created. Thread, pool, and thread are background threads. Each thread uses the default stack size, runs at default priority, and is in a multithreaded unit. If a thread is idle in managed code (such as waiting for an event), the thread pool will insert another secondary thread to keep all processors busy. If all thread pool threads are always busy, but the queue contains pending jobs, the thread pool will create another secondary thread after a period of time, but the number of threads will never exceed the maximum. Threads that exceed the maximum value can line up, but they don't start until other threads are finished.
